Abstract

A support (10) is disclosed for use with food service equipment. The support has a tubular upper portion (11) and a tubular lower portion (12) telescopically mounted within the upper portion for adjustable vertical movement. The upper portion has a support body (15) and a steel, externally threaded stud (17). The lower portion includes a plastic, tubular foot (20) having a channel (21) with a t-shaped portion defined by a first portion (22) and a second portion (23). The lower portion also includes a t-shaped metal insert (25) mounted within the t-shaped portion of the channel. The insert is threaded onto the bottom end of the threaded stud for threaded vertical movement along the stud.

Claims

1. A height adjustable support for supporting food service equipment at different elevations above a supporting floor, the height adjustable support being adapted to be mounted to the bottom end of the food service equipment, and which comprises an upper portion and a lower portion, said upper portion having a tubular body and an externally threaded stud fixedly mounted concentrically within said tubular body, said stud having a top section and a bottom section opposite said top section, said lower portion having a foot with a channel therein having a channel first portion adjacent a top end of said foot with a select internal diameter and a channel second portion spaced from said top end and extending from said channel first portion, said channel second portion having an internal diameter less than said channel first portion internal diameter, the height adjustable support lower portion also including an internally threaded insert adapted to be threadably coupled to said stud bottom section, said insert having an insert first portion with a first select external diameter configured to be received tightly within said foot channel first portion and an insert second portion with a second select external diameter smaller that said channel first portion first select external diameter and configured to be received tightly within said foot channel second portion, wherein said foot channel also includes at least one projection and wherein said insert second portion contacts said at least one projection, whereby the support may be coupled onto a food service equipment by threading the top section of the stud into the equipment and whereby the height of the equipment may be adjusted by threadably positioning the lower portion along the bottom section of the threaded stud.

2. The support of claim 1 wherein said at least one projection of said channel comprises an annular array of longitudinally extending ribs.

3. The support of claim 1 wherein said lower portion is a wheel assembly.

4. A height adjustable support for supporting food service equipment at different elevations above a supporting floor, the height adjustable support being adapted to be mounted to the bottom end of the food service equipment, and which comprises a leg having a body with a central passage therethrough, an externally threaded stud fixedly mounted within said body central passage, and a plastic foot having a channel therein including a t-shaped channel portion adjacent a top end of said foot, said foot also including a t-shaped insert having a threaded passage therein configured to threadably receive said stud for threaded movement along said stud, said t-shaped insert being tightly received within said t-shaped channel portion, wherein said foot channel also includes at least one projection and wherein said t-shaped insert contacts said at least one projection whereby the support may be coupled to a food service equipment by threading the top end of the threaded stud into the equipment and whereby the height of the equipment may be adjusted by threadably positioning the foot along the lower end of the threaded stud.

5. The support of claim 4 wherein said at least one projection of said channel comprises an annular array of longitudinally extending ribs.

6. The support of claim 4 wherein said foot is a wheeled leg.

7. A height adjustable support for supporting food service equipment at different elevations above a supporting floor, the height adjustable support being adapted to be mounted to the bottom end of the food service equipment, and which comprises,

a leg with an externally threaded stud,

a plastic foot having a channel therein with a first channel portion of a select size and a second channel portion extending from said first channel portion and having a select size smaller than said first channel portion select size, and

an insert having a threaded passage therein configured to threadably receive said stud for threaded movement along said stud, said insert having a first insert portion configured to conform with said foot first channel portion and a second insert portion extending from said first insert portion and being configured to conform with said foot second channel portion,

wherein said foot channel also includes at least one projection and wherein said second insert portion contacts said at least one projection,

whereby the support may be coupled to a food service equipment by threading the top end of the threaded stud into the equipment and whereby the height of the equipment may be adjusted by threadably positioning the foot along the lower end of the threaded stud.

8. The support of claim 7 wherein said at least one projection of said channel comprises an annular array of longitudinally extending ribs.

9. The support of claim 7 wherein said foot is a wheeled leg.
